To albwh'cm tv may couccrm- Beit known that-l, PHILIP T. I l'ANDIeEs,- a

citizen of i the United States, residing at Detroit, county of Wayne,Stateof ll'lichi,f., 'an,

have invented a certain new and useful gImproveme'ntin Car-Couplersand`I declare the fellowin g to be a full, clear, and exactdescription-of the invention, such as will enable oth- .ers skilled' inthe art to which it appertains to make and use the same, referencebeinghad to the accompanying drawings, which forma partofthisspecification.

My invention has for its object certain new and useful improvement-sinfcar-couplers and it consists of the construction,combination, andarrangement of devices' hereinafter de.-

scribed and claimed, and illustrated inthe .ac-

" companying drawings, .in which- Figure `1 is a vertical section inside elevation; Fig. 2`isga horizontaljsection on the line' 2 2, Fig'.1." Fig. 3 is a similarsectin of parts'of the.device,.bu t showingthelocking-pin. iin' locked -position. 4Figifl is a 'viemin elevation ofthe locking-pin.` Fig. '5

lMore particularly n ry invention. has for its object acar-coupler-havin g an improved locking device Wherebywhen the pinisfwithdrawn foruncouplingit will be brought-into posifion, in the actof u ncouplin g, to automatically' dropv into loekedposition vin the actof coupling adjacent cars, requiring noattendant to seat the pin' inlocked position. Y

I Obviously acoupler provided with a locking device which`onlyneedsthcattention of an attendant to threw the-pin into unlocked thelocking device into locked position -in the act of couplingcars withoutany further atf tention is a matter of great yconvenience andi f L iutilityL,

It is the purpose locking deviceof superior eiiioiency and simplicit'y.

I carry' out my 'invention .as follows :v

The locking-pin is constructedon'the side 'adjacent to the stop Dwitlia shoulder c,

Thelock- The knuckle ll sheld in place in the coupler by the customarypivot-pin ll', but the inner end of the knuckle is formed with aprojecting shoulder (indicated at 132) projecting rearward and outwardat one side the locking-pin in locked position, the head A' beingrecessed, as indica-ted at a?, to permit the shoulder 13.2 ofthe'knucklc swinging in out of the way of the locking-pin in the act ot'coupling. 'lhe knuckle adjacent to the locking-pin is cut away slightlyat a suitable point (indicated, for example, in Figs. 2 and 3 at b) tocontact with the cut-away surface at c2 on the lower end Cof thelocking-pin in the act o`t` uncoupling, and thereby throw the pin downoff the ledge a and upon the upper surface of the shoulder 132 of theknuckle.

In Fig. 1 the locking-pin C is shown in raised position ready foruneoupling. By reference to Fig. 8 it will readily be seen that when thepin C is lifted by the device E the shoulder c of the pin striking thestop D will cause the pi-n to be tilted, thereby engaging the shoulderc' of the pin upon the ledge a of the coupler-head. The attendant maythen leave the coupling mechanism altogether. The further action of thelocking device isa-s follows: In the act of uneouplingthe adjacent edge,as the point b of the knuckle is in the act of uneoupling and as theknuckle is being thrown open, willeontact with the lower end c ofthelocking-pin, which projects beneath the shoulder c'. As the knuckleis swung open this contact thereof with the lower end of the pin willthrow the .shoulder c' of the locking-pin ofi` the ledge a' of thecoupler- `head int-o the position indicated in dotted lines at thenumeral 5, Fig. 1, the shoulder c' of the locking-pin resting upon theshoulderz of the knuckle and the lower end c of the pin projectingdownward alongside the adjacent face of the knuckle, permitting the carsto be uncoupled, while the locking-pin is also supportedv in positionlfor coupling. lVhen the corresponding knuckle engages with the openknuckle B, it will of course throw the knuckle B back into lockedposition, and in so 4doing the rear end of said knuckle will ride outfrom under the shoulder c of the locking-pin, allowing said pin toautomatically drop into locked position. (Indicated in Fig. 3.) TheshoulderB2 of the knuckle Bis so formed, together with other parts ofthe device, that-,said shoulder will never ride outward from under theshoulder c of the locking-pin.

It will be evident that the parts which hold the locking-pin insuspended position are not movable parts, but that instead they alwaysremain in fixed posit-ion. In the position indicated in Fig. 1 thelocking-pin seats on the head and not on the knuckle.

This construction and arrangementof parts permits, as will be observedby reference to Fig. 3, a very effectual closing of the mouth ofthe headof the draw-bar when the cars are coupled together, thereby excludingdirt, sleet, tbc., from entering the mouth of the draw-head and impedingthe working el. the mechanism.

'lhc cut-away portion c of the locking device and the cut-away portierib of the knucklc form canrsurfaccs, whereby the locking device will betripped ofl` its fixed support on the opening movement of the knuckle.
